Who we are
A Custom Headwear Manufacturer and Trading Partner in Dongguan, China
HJ CAPS is the abbreviated brand name derived from the initials of the company’s Chinese name. Our sales operations and manufacturing activities are based in Dongguan, bringing customer communication, product development, production coordination and headwear manufacturing together within one business structure.
For more than 10 years, we have focused on custom headwear projects for international customers. We help turn product requirements into workable samples and support projects through production, quality control and shipment.
Production capacity varies by product type, materials, customization and production schedule.
What we make
Custom Headwear Across Multiple Product Categories
We develop product specifications around the intended design, market and production requirements rather than limiting buyers to fixed catalog products.
Customization can include panel construction, crown shape, brim style, materials, colors, closures, embroidery, patches, labels and packaging, subject to project feasibility.

Bulk production begins only after the final sample and production details have been approved.
